Revisão taxonômica de Colatooeciidae Winston, 2005 (Bryozoa, Cheilostomata)

Abstract

Colatooeciidae comprises Colatooecia, Cigclisula and Trematooecia. While Colatooecia has been considered a well-defined genus, the discrimination between Cigclisula and Trematooecia is very confused. Therefore, the taxonomic review of Colatooeciidae was made with the aim to elucidate the morphological problems related mainly with Cigclisula and Trematooecia. We redescribed the type species of Cigclisula and designated and redescribed the type species of Trematooecia. Diagnostic characters of both genera are redefined. Five new species of Cigclisula are described: Cigclisula n. sp. 1, Cigclisula n. sp. 2, Cigclisula n. sp. 3, Cigclisula n. sp. 4 and Cigclisula n. sp. 5. Four species previously assigned to Cigclisula are transferred to Trematooecia: Trematooecia arborescens (Canu & Bassler, 1928) n. comb., Trematooecia gemmea (Winston & Woollacott, 2009) n. comb., Trematooecia hexagonalis (Canu & Bassler, 1930) n. comb., and Trematooecia verticalis (Maplestone, 1910) n. comb. Two species previously assigned to Trematooecia are transferred to Cigclisula: Cigclisula turrita (Smitt, 1873) n. comb. and Cigclisula psammophila (Winston & Håkansson, 1986) n. comb.
